FRANZ KfiOUREK, OF MIES, AUSTRIA-HUNGARY.

TURBINE.

To all whom it may concern Be it known that I, FRANZ Kfiounnx, a subject of the Emperor of Austria-Hungary, and resident of Miss, Bohemia, Austria- Hungary, have invented a new and Improved Turbine, of which the following is a clear, full, and exact description.

This invention relates to improvements in turbine motors, the primary object of the improvement being to provide means where by the water, steam or other fluid employed will traverse in substantially a plurality of circular channels to cause the rotor and its casing to revolve.

A further object of the invention is to provide means for controlling the flow of the motive fluid so as to cause the latter to pass through the channels in any number of plates forming the rotor and to provide means for reversing the rotor, whereby to provide convenient and effective means for controlling the motor.

Another object of the present invention is to provide improvements in the means employed in the channels to produce the most effective forceof the fluid.

The invention also comprehends improvements in the details of construction and ar i'angement of parts which will be hereinafter described and particularly pointed out in the claims.

In the accompanying drawings: Figure 1 is a longitudinal central section of my improved motor, the reversing valves being in full lines; Fig. 2 is a transverse section on the line AB of Fig. 1; Fig. 3 is a detail section on the line CD of Fig. 2; Fig. 4 is a detail section on the line EF of Fig. 2; Fig. 5 is an end elevation of the central portion of the motor; Fig. 6 is a detail cross section on the line KL of Fig. 7 Fig. 7 is a detail section on the line G-H of Fig. 6; Fig. 8 is a detail section on the line PQ of Fig. 9; Fig. 9 is a detail section on the line M-N of Fig. 8; Fig. 10 is a detail perspec-- tive view of one of the water deflectors; Fig. 11 is a detail longitudinal section of a slightly modified form of the invention; and Fig. 12 is a detail sect-ion of the end of one of the screw stems and its gear, for operating the controlling valves.

and 8. Plate 2 forms the end of a casing and ]S of greater diameter than the companion plates. The casing is formed, in addition to the end plate, by a plurality of rings 18, and a head 9, the rings being spaced from the peripheries of the plates to form an annular passage 26, while the head 9 is spaced from plate 8 to form a fluid chamber 19, with which passage 26 communicates. End plate 2 is formed with a central tubular extension 10, through which the fluid flows to the rotor, while head 9 is formed with a central tubular extension 11, through which the fluid flows from the rotor. End plates 2 and 5 are each provided on one surface with a plurality of concentric ribs 12, 13, 1a, 15, 16 and 17, and the other plates have similar ribs, but extending from both flat surfaces of said plates. These ribs are spaced apart and when the plates are assembled in position on the shaft, form a plurality of concentric channels, as clearly shown in Fig. 2. The ribs are mutilated to receive reversing valves 26, operating in seats 27 formed in the faces of adjacent plates. The reversing valves are exactly alike, and but one will be described. Valve 26 comprises a tapered plug and a stem 38, the latter operating in a bearing on the casing. In the plug portion of the valve are inclined ports 32, 33, 34, 35, 36 and 37, the inclination of said ports being such as to form communication between successive concentric channels. The inner end port 32 is in constant communication with the space in the hub of the plate, inside the rib 12, while port 37 is so formed as to be in constant communication with the passage 26. By turning the reversing valves half a revolution from the position shown in Fig. 2, the course of the fluid will be reversed, hence the motor will be reversed.

To the stems of each reversing valve is secured a pinion 39, the pinions being of such diameter as to mesh, as indicated in Fig. 1. Mounted to slide on the periphery of the casing is a ring provided with teeth 10, which mesh with the end pinion 39. The ring 10 may be operated in any suitable manner to change the position of the valves.

Extending from rings on the periphery of the casing are two spaced apart lugs 42 and i3, and extending from the ring tO is a lug 4-1. Now if the ring 40 be held and the easing is rotated, obviously the lug 12 will contact with lug 41 and move the latter up to the next lug 4-3, and vice versa. This movement is timed to rotate the reversing valves one-half revolution.

Each of plates 2, 3, 4c, 5, 6, 7 and S is formed with a series of horizontal alined openings 21, 22 and 24, located inside the plane of the inner ribs 12. The openings in the plates are in alinement, and communicate with chambers 23. Extending through the respective openings are screws 25, which stems fit in bearings formed in the end plates 2 and 8. On the screws are threaded valves 24? formed with extensions 24;", which fit in grooves to form guides.

On the end of each screw 25 is a pinion 414, and meshing with said pinions are inner and outer toothed rings 46 and 45, which operate in guides 45. The toothed rings rotate with the casing, hence to rotate the screws; either means may be provided to hold one or the other of the rings, which of course will retate the pinions.

The valves 24: are for the purpose of controlling the fluid, so that as many of the channels in the plates may receive the fluid as may be selected to obtain the desired power and speed. Obviously by rotating the screws 25, the valves 246 are moved in the alined openings, so that the fluid can be cut off from as many plates in the series as might be selected. For instance, as shown in Fig. 1 only, the channels formed between the plates 2, 3 and 4: will receive the fluid, for obviously, as the openings in the next plate are closed, the fluid is prevented from going farther,

In order to add to the efficiency of the fluid passing through the channels formed between the ribs on the plates I insert baflies 47, shown in Figs. 6, 7 and 10. The central batfles comprise two spaced apart plates 47, connected by a web 52, from the ends of which extend legs 48. Each plate 47 is bulged at the center, and inclined toward the ends of the adjacent plate, but the opposite ends of both said plates are slightly spaced to form an opening. The outermost battles are similar to those in the middle of the channels, except that but a single plate is employed, and the ends of this one are slightly spaced from the ribs, as clearly shown in Fig. 7 The legs as fit in grooves 50 formed in the walls of the channels, which aflord convenient means for holding the baffles in position. The battles shown in Figs. 8, and 9 are disposed at right angles to those shown in Figs. 6, 7 and 10, the legs 48 fitting in grooves 50.

In the form of the invention shown in Fig. 11, the circular plates 2', 3', l and 5 are formed on their flat surfaces with grooves, in which rings 16 fit to form the channels. The outer rings 17 which form the outer walls of the rotor are formed wit-h grooves to receive the edges of the plates.

In operation the fluid passes through the tubular extension 10, and into the chamber 23, from thence it passes through the port 32, and around the first channel, and from the latter through port 33, and so on until port- 37 is reached. From port 37 the fluid passes into the passage 26, thence to cham ber 19 and out the tubular extension 11. In passing through the channels, the fluid is caused to take a. circuitous path, due to the disposition of the bafiies 47. The pointed ends of the battles are disposed parallel or perpendicular to the axis of the motor, thus the inrushing fluid passes through the open ends of the batlles and acts against the middle wall thereof and serves to impart motion to the rotor. I find that I obtain a higher degree of etliciency by making the bafiles hollow, as the pressure of the fluid acting from the inside is concentrated. Furthermore, because of the shape and disposition of the baflles, the fluid acts on both halves of each battle producing inside pressure in the front half and inside dilatation in the rear half of the baflies. To reverse the motor, the ring 10 is operated as previously described, and through the pinions 39, the valves are turned half revolution, and because of the construction of the ports the fluid will be caused toflow in the opposite direction in the channels. When the fluid enters the chamber 23, and if the controlling valves 2 1. are positioned back in the seats in the end plate 8, said fluid will flow through the openings 21, 22 and 24, to the next chamber 23, and so on throughout the series of plates. The result isthe fluid will flow through the channels in all the plates. Now if it be desired to reduce the power of the motor, the screws 25 are operated as previously described, and the valves 24; are advanced; for instance, to the position shown in Fig. 1, hence the fluid cannot flow through the openings 21, 22 and 24, of plates 5, 7 and 6.
